Hairy cell leukemia (HCL) is a rare, slow-growing blood cancer in which the bone marrow makes too many of certain white blood cells. The antibody Rituximab binds to a protein in cancerous white blood cells and is often used to treat HCL. Researchers want to see if combining it with the drug Moxetumomab pasudotox-tdfk (also called Lumoxiti) can fight HCL better.
To test the safety of Moxetumomab pasudotox taken with Rituximab for people with HCL or HCL variant.
People age 18 years and older with HCL or HCL variant that has not responded to standard therapy
Participants will be screened with:
Blood, heart, and urine tests
Test of blood oxygen levels
Review of bone marrow. This can be from previous test results or a new sample.
Participants will get the study drugs in up to 8 cycles. A cycle will last about 28 days.
Both drugs will be given through a plastic tube in a vein.
In the first week of cycle 1, participants will have:
1 visit to get Rituximab for 7.5 hours
3 visits to get Lumoxiti for 30 minutes per infusion
In the first week of cycles 2-8, participants will have:
- visit to get Rituximab for 2-4 hours and Lumoxiti for 30 minutes
- visits to get Lumoxiti for 30 minutes per infusion
Participants will be asked to drink lots of water and take aspirin during the cycles. They will get drugs to minimize allergic reactions.
Participants will repeat screening tests at visits throughout the cycles and 1 follow-up visit. They may have an eye exam.

Moxetumomab Pasudotox-tdfk + Rituximab
Drug: Moxetumomab Pasudotox-tdfk
Moxetumomab pasudotox-tdfk is administered at 30-40 ug/Kg iv over 30 min given on days 1, 3, 5 of each cycle.
Rituximab will be administered at 375mg/m^2 iv, 50-400 mg/hr. On cycle 1, Rituximab is given on day -2, on subsequent cycles, Rituximab is given on day 1.
- safety and toxicity [ Time Frame: 4 weeks ]Determine recommended safe dose of moxetumomab pasudotox-tdfk and rituximab .
- Response rates [ Time Frame: 1, 2 and 3.5 years after EOT, then every 2 years ]Percentage of patients whose cancer shrinks or disappears after treatment
- MRD-free rates [ Time Frame: 1, 2 and 3.5 years after EOT, then every 2 years ]Percentage of patients without minimal residual disease
- Response duration [ Time Frame: 1, 2 and 3.5 years after EOT, then every 2 years ]Time of initial response until documented tumor progression
